BQD315 - 15Amp Circuit Breaker

BQD315 - 15Amp Circuit Breaker

The Siemens BQD315 is a 15-amp, 3-pole circuit breaker built for 480/277VAC three-phase systems. It protects your branch circuits, panelboards, and connected equipment from overloads and short circuits. The thermal magnetic trip unit responds to prolonged overcurrents and sudden faults, helping reduce the risk of damage while keeping your system operating efficiently.

This breaker is designed for panelboard mounting and uses low-tab connections for quick and secure installation.
